EC2 + IAM Exam Checklist
- Know how to SSH into EC2 (and change .pem file permissions)
- Know how to properly use security groups
- Know the fundamental differences between private vs public vs elastic IP
- Know how to use User Data to customize your instance at boot time
- Know that you can build custom AMI to enhance your OS
- EC2 instances are billed by the second and can be easily created and thrown away, welcome to the cloud! Maybe on Exam:
- Availability zones are in geographically isolated data centers
- IAM users are NOT defined on a per-region basis
- If you are getting a permission error exception when trying to SSH into your linux instance, then the key is missing chmod 400 permissions
- If you are getting a network timeout when trying to SSH into your EC2 instance, then your security groups are misconfigured
- Security groups reference IP address, CIDR block, Security group, but NOT DNS name
